Description

Technical Field

[0001] The utility model relates to the technical field of beverage preparation equipment, and in particular to a brewing module applied to beverage preparation equipment. Background Art

[0002] A coffee machine is a machine that can grind coffee beans into powder and brew coffee. In the existing coffee making process, the coffee beans are first ground into powder by a grinding device, and then the coffee powder is discharged into the container body of the brewing device at the powder receiving position, and then the coffee powder received in the container body is pressed into a powder cake by a pressing mechanism, and finally the pressed powder is brewed and extracted to make coffee. However, in the process of the container body receiving the coffee powder, the coffee powder is accumulated into a pointed cone shape due to the concentration of the falling points of the coffee powder. If the coffee powder falls into the container body unevenly, the subsequent pressing will cause part of the powder cake to be dense and part to be loose. The water flow during extraction will choose the place that is easier to pass because of its inertia, that is, it will be easier to pass through the loose place, so this part will be extracted more, and the dense place will be insufficiently extracted, resulting in uneven extraction, which directly affects the stability of your extracted coffee and the taste of the coffee after extraction. It is easy to affect the pressing force and the balance of force during the pressing process, and it is easy to cause flying powder, resulting in poor pressing effect and affecting the preparation quality of coffee.

[0053] See also Figures 1 to 4 The present invention provides a brewing module for a beverage preparation device, including a container assembly 200 and a driving mechanism 300. The container assembly 200 is provided with a feed inlet and a brewing cavity 211 for receiving and brewing powder, and the powder enters the brewing cavity 211 through the feed inlet. The container assembly 200 is provided with a movable part that can push the powder to reciprocate in a vertical direction, so as to drive the powder to spread evenly in the brewing cavity 211 during its vertical movement. The driving mechanism 300 is drivingly connected to the movable part of the container assembly 200.

[0054] In other embodiments, the driving mechanism may drive the container assembly to reciprocate relative to the movable member inside the container assembly, or the driving mechanism may drive both to move simultaneously.

[0055] In the technical solution provided by the utility model, after the powder material ground and discharged by the grinding device enters the brewing chamber 211 from the feed port, it is accumulated in the cavity of the brewing chamber 211 in the shape of a pointed cone; in the process of the brewing chamber 211 receiving the powder material, and / or when the brewing chamber 211 completes the operation of receiving the required amount of powder material, and / or before the pressing mechanism 400 performs the pressing operation on the powder material, since the movable part can reciprocate up and down, the powder material located at the top of the pointed cone is accelerated to slide down during its vertical movement, so that the coffee powder tends to be evenly spread on the bottom cavity wall of the brewing chamber 211, forming a relatively flat surface to be pressed, which is more conducive to the subsequent balanced pressing of the pressing mechanism 400; at the same time, the coffee powder is also stably fixed on the bottom cavity wall of the brewing chamber 211, avoiding the occurrence of flying powder or falling powder, which helps to improve the pressing reliability of the subsequent pressing mechanism 400 as a whole, and finally optimizes the preparation quality of the coffee.

[0056] The beverage preparation machine in the present design can be an intelligent fully automatic or semi-automatic beverage equipment, such as a coffee machine, a soybean milk machine, etc. Correspondingly, the granular material involved in the present utility model can be a bean material such as coffee beans and soybeans. For ease of understanding, the following embodiments are all described by taking the beverage preparation equipment as a coffee machine as an example, wherein the granular material refers to coffee beans, and the powder material refers to coffee powder.

[0057] It can be understood that the beverage preparation machine generally includes a grinding device and a brewing device. Among them, the grinding device grinds and pierces the coffee beans through a knife such as a knife disc to obtain coffee powder. The brewing module in the brewing device receives the powder formed by the grinding device, and evenly spreads the powder stacked in a pointed cone shape; the additional pre-set pressing mechanism 400 in the brewing device presses the powder stacked in the brewing chamber 211 into a cake; the additional pre-set liquid supply mechanism in the brewing device provides sufficient and required type of liquid (such as hot water) for the coffee powder pressed into a cake, and finally realizes the extraction and brewing of coffee.

[0058] In view of the above, the present design mainly improves the structure of the brewing module in the brewing device, and the rest, such as the pressing mechanism 400 and the liquid supply mechanism, can refer to the prior art and will not be described in detail in the present design.

[0059] In the present design, the brewing module used in the beverage preparation device may also include a base 100, and the base 100 may be installed on the container assembly and the drive mechanism. It is understood that the base 100 may be a plate-like structure, a block-like structure, a box-like structure, a frame-like structure, or other suitable structures for installation of, for example, the container assembly 200 and the drive mechanism 300, which are dedicated to the brewing module. Alternatively, the base 100 may also be a structure shared with a certain structure of the entire beverage preparation device (such as a housing), or a structure shared with other components in the beverage preparation device (such as a grinding device), without limitation.

[0060] The base 100 defines a powder receiving position 110 and a brewing position 120, and the powder receiving position 110 and the brewing position 120 are spaced apart in the horizontal direction. The container assembly 200 can be reciprocated between the powder receiving position 110 and the brewing position 120. The discharge port of the grinding device can be arranged above the powder receiving position 110, and the feed port of the brewing chamber 211 in the container assembly 200 can be arranged at the powder receiving position 110 or below the powder receiving position 110, so that the coffee powder obtained by grinding by the grinding device falls into the brewing chamber 211 under the action of gravity. The feed port in the container assembly 200 is generally arranged on the top cavity wall of the brewing chamber 211, so that the coffee powder entering the brewing chamber 211 will naturally accumulate on the bottom cavity wall of the brewing chamber 211, and present a pointed cone shape with a small cross-sectional area at the top and a large cross-sectional area at the bottom. The above-mentioned pressing mechanism 400 and liquid supply mechanism mainly act at the brewing position 120, so that when the container assembly 200 moves to the brewing position 120, the pressing mechanism 400 presses the coffee powder in the container assembly 200, so that the coffee powder is pressed into a cake; the liquid supply mechanism acts on the coffee powder in the container assembly 200 to extract and brew the coffee powder in the container assembly 200.

[0061] Driven by the driving mechanism 300, the movable part reciprocates in the vertical direction. On the one hand, during the vertical movement of the movable part, the coffee powder on the top of the cone-shaped bottom cavity wall of the container assembly 200 can be driven to slide down, thereby making the stacking area of ​​the coffee powder evenly flat; on the other hand, the vertical movement of the movable part will not affect the accurate alignment between the feed port of the brewing cavity 211 and the discharge port of the grinding device, thereby reducing the loss of coffee powder in the receiving process and not occupying horizontal space.

[0062] In one embodiment, the container assembly 200 includes a container body 210 and a piston member 220, wherein the container body 210 is provided with a material receiving channel in the vertical direction; the piston member 220 is sealed in the material receiving channel and defines the brewing chamber 211 together with the material receiving channel, and the upper end surface of the piston member 220 constitutes the bottom cavity wall of the brewing chamber 211, and the piston member 220 can reciprocate in the brewing chamber in the vertical direction. The piston member 220 constitutes the above-mentioned movable component.

[0063] The container body 210 is roughly in the shape of a hollow column extending in the vertical direction, with an open upper end to form a feed port; the lower end is also open to allow the piston member 220 to extend into and reciprocate up and down in the material receiving channel. The outer shape of the piston member 220 is adapted to the inner shape of the material receiving channel to reduce the installation gap formed between the two. At least the outer periphery of the piston member 220 is made of an elastic sealing material, or an elastic sealing ring layer is arranged on the outer periphery of the piston member 220, so that the outer wall of the piston member 220 is sealed against the inner wall of the material receiving channel, thereby realizing dynamic sealing during the vertical movement of the piston member 220 relative to the container body 210, and preventing coffee powder or coffee beverage after extraction and brewing from overflowing.

[0064] Before the container body 210 receives the powder, the driving mechanism 300 drives the piston 220 to move to a preset position in the material receiving channel. After the container body 210 receives the powder and before the pressing mechanism 400 presses the powder in the container body 210, the driving mechanism 300 can drive the piston 220 to reciprocate in the vertical direction at a preset speed for a preset number of times and then stop, and in this process, the coffee powder can be evenly spread on the bottom wall of the brewing chamber 211.

[0065] For ease of understanding, the vertical movement stroke of the piston member 220 is specifically described below:

[0066] See also Fig. 9 In one embodiment, the vertical movement stroke of the piston member 220 includes a first stroke H1 in the container body 210 for cooperating with the pressing mechanism 400 to press the powder for brewing and extraction. In this stroke, the container assembly 200 is at the brewing position 120. The pressing component (such as another piston member) in the pressing mechanism 400 moves vertically downward, and the piston member 220 can move vertically upward, so that the pressing component and the piston member 220 are close to each other, and the powder is pressed into a cake. Among them, the whole process of the piston member 220 moving vertically upward is the first stroke H1.

[0067] See also Figures 6 to 8 In one embodiment, the vertical movement stroke of the piston member 220 also includes a second stroke H2 for evenly spreading the powder in the container body 210. In this stroke, the container assembly 200 can be at the brewing position 120. Before the pressing component moves vertically downward, the piston member 220 can perform at least one vertical upward movement, so that the powder accumulated on the piston member 220 is evenly spread. At this time, the entire process of the vertical movement of the piston member 220 is the second stroke H2.

[0068] It can be understood that the first stroke H1 is used for pressing powder and requires a larger stroke volume, while the second stroke H2 is used for vibrating loose powder and its amplitude does not need to be set too large, that is, a relatively small stroke volume is required. Therefore, in specific applications, the second stroke H2 can be set to be smaller than the first stroke H1.

[0069] In addition, in a specific application, if the speed of the piston member 220 during the first stroke H1 is defined as V1, and the speed of the piston member 220 during the second stroke H2 is defined as V2, wherein V1 is less than V2. In this way, by appropriately increasing the speed V2 of the second stroke H2, the vibration powder spreading process of the piston member 220 has a relatively higher vibration frequency, which helps to achieve the purpose of evenly spreading powder more efficiently.

[0070] The preferred implementation is: the piston member 220 is quickly raised to a preset powder shaking high position at a speed of V2, and then quickly returns to a preset powder shaking low position at the same speed V2 to complete a powder shaking stroke. The second stroke H2 is composed of at least one powder shaking stroke. In specific applications, the second stroke H2 can be composed of, for example, two consecutive powder shaking strokes. Then the piston member 220 pushes the powder upward to the powder pressing position at a speed of V1 to cooperate with the upper piston to press the powder into a powder cake, wherein V1 is less than V2.

[0071] In one embodiment, the vertical movement stroke of the piston member 220 also includes a third stroke H3 in the container body 210 for pushing the powder residue upward out of the container body 210 after the powder is extracted, wherein H3 is greater than H1. In this stroke, the container assembly 200 is at the brewing position 120. When the pressing component moves vertically downward and the piston member 220 moves vertically upward, the powder is pressed into a cake; and after the liquid supply assembly completes the extraction and brewing operation of the powder cake and takes out the coffee beverage, there may be residue on the inner wall of the container body 210 and the upper end surface of the piston member 220. At this time, the piston member 220 moves vertically upward, and the residue on the inner wall of the container body 210 and the upper end surface of the piston member 220 can be pushed upward to the outside of the container body 210. At this time, the entire process of the piston member 220 moving vertically upward is the third stroke H3. At this time, the third stroke H3 is set to be greater than the stroke amount of the first stroke H1, so that the piston member 220 can fully move upward to at least partially extend out of the container body 210.

[0072] There are many solutions of the driving mechanism 300 to achieve the above purpose:

[0073] In one embodiment, the driving mechanism 300 includes a first driver, which is disposed on the seat body 100 and has a telescopic output shaft that can reciprocate and telescope in the vertical direction, and the telescopic output shaft is connected to the piston member 220. Specifically, the first driver is, for example, a linear cylinder, which can be integrally disposed on the lower side or the side of the container body 210. When the linear cylinder is disposed on the side of the container body 210, the driving mechanism 300 may further include a transmission member, which can transmit the telescopic motion of the telescopic output shaft to the piston member 220, thereby driving the vertical motion of the piston member 220.

[0074] In addition, in another embodiment, the driving mechanism 300 includes a second driver 310, a driving rod 320 and a guide member 330. The second driver 310 is provided on the seat body 100 and has a rotating output shaft rotatably provided along a vertical axis; the driving rod 320 is respectively installed on the seat body 100 rotatably along a vertical axis and translatably along a vertical direction, the driving rod 320 is connected to the rotating output shaft to be driven by the rotating output shaft to rotate along a vertical axis, and the driving rod 320 is connected to the piston member 220; the guide member 330 is fixed relative to the container body 210 and connected to the driving rod 320, ... One of the connections between the member 330 and the driving rod 320 is provided with a guide groove 321, and the other is provided with a guide protrusion slidably connected to the guide groove 321; wherein, the vertical movable stroke of the piston member 220 includes a first stroke H1 in the container body 210 for cooperating with the pressing mechanism 400 to press the powder for brewing extraction, a second stroke H2 in the container body 210 for evenly spreading the powder, and a third stroke H3 in the container body 210 for pushing the powder residue upward out of the container body 210 after the powder is extracted.

[0075] Specifically, the second driver 310 is, for example, a motor, which can be arranged on the upper side, lower side or side of the container body 210. The rotation output shaft of the motor extends in the vertical direction so that it can rotate along its own axis when starting operation. The drive rod 320 also extends in the vertical direction and is directly or indirectly connected to the rotation output shaft so as to be able to convert the rotation of the rotation output shaft into its own vertical movement in the vertical direction. The drive rod 320 and the piston member 220 can also be directly or indirectly connected. The guide member 330 is fixed relative to the container body 210, so that when the guide protrusion slides along the guide groove 321 and is guided, the drive rod 320 is driven to move relative to the container body 210.

[0076] In one embodiment, the guide groove 321 includes a third groove section 321c extending in the vertical direction, so that when the guide protrusion slides along the third groove section 321c, the rotational motion of the drive rod 320 along the vertical axis is converted into the translational motion of the piston member 220 along the vertical direction; the first stroke H1, the second stroke H2 and the third stroke H3 are all formed by the stroke of the guide protrusion sliding vertically in the third groove section 321c. The third groove section 321c is extended and arranged in the vertical direction, and can convert the rotation of the drive rod 320 along the vertical axis into the translational motion along the vertical direction during the sliding of the guide protrusion along the third groove section 321c, and finally achieve the purpose of driving the piston member 220 to translate in the vertical direction.

[0077] Specifically in one embodiment, the third groove section 321c can be configured to extend spirally along the vertical direction and the circumference of the driving rod 320, respectively, so as to achieve the purpose of converting the rotational motion of the driving rod 320 into the up and down translational motion of the piston member 220. Or in one embodiment, the driving mechanism 300 further includes a driving gear 340 and a driven gear 350, wherein the driving gear 340 is coaxially mounted on the rotating output shaft; the driven gear 350 is arranged beside the driving gear 340 and meshes with the driving gear 340; wherein the driven gear 350 is provided with an internal thread, and the driving rod 320 is provided with an external thread, and the internal thread is threadedly connected with the external thread. In this way, by adjusting the gear ratio of the driving gear 340 and the driven gear 350, the rotation deceleration or rotation acceleration of the rotating output shaft to the driving rod 320 can be achieved accordingly. The arrangement of the internal thread and the external thread helps to realize the combination of the two motion forms of the drive rod 320 rotating along the vertical axis and translating along the vertical direction under the drive of the first driver, the driving gear 340 and the driven gear 350, and convert it into the spiral translation of the drive rod 320. At this time, the third groove section 321c can be arranged to extend substantially parallel to the axial direction of the drive rod 320, which is easier to process and shape.

[0078] Based on any of the above embodiments, further refer to Figure 5The guide groove 321 also includes a second groove section 321b extending along the circumference of the driving rod 320, and a first groove section 321a extending along the vertical direction, the second groove section 321b has a first end and a second end which are arranged opposite to each other in the circumference of the driving rod 320, the first end is connected to the third groove section 321c, and the second end is connected to the first groove section 321a, so that when the guide protrusion slides to the first end, the container body 210 is driven to be located at the brewing position 120, and when the guide protrusion is located at the second end, the container body 210 moves to the powder receiving position 110; another embodiment is that the first stroke H1, the second stroke H2 and the third stroke H3 are all formed by the stroke of the guide protrusion vertically sliding in the third groove section 321c.

[0079] Specifically, the guide groove 321 also includes an entry groove section 321e. It can be understood that, taking the guide groove 321 being set on the outer peripheral side wall of the driving rod 320 as an example: the driving rod 320 includes a threaded rod section and a guide rod section connected in sequence from top to bottom, and the threaded rod section is formed with an external thread and is threadedly connected and matched with the internal thread of the driven gear 350. The guide groove 321 is set at the guide rod section. The outer diameter of the guide rod section is larger than the outer diameter of the threaded rod section, so that a step surface is formed at the connection between the guide rod section and the threaded rod section. The entry groove section 321e penetrates downward from the step surface to connect the third groove section 321c or the second groove section 321b, so that the guide protrusion can slide into the entry groove section 321e from top to bottom, and directly be located at the third groove section 321c, or move to the third groove section 321c via the second groove section 321b.

[0080] The entry groove section 321e is connected to the first end of the second groove section 321b, and when the guide protrusion enters from the entry groove section 321e and slides to the first end of the second groove section 321b, the container body 210 is in the brewing position 120. Further, in the circumferential direction of the driving rod 320, the second groove section 321b gradually extends obliquely toward one axial end of the driving rod 320, which helps to decelerate the rotation speed of the container body 210 when switching between the powder receiving position 110 and the brewing position 120, so that the rotation process of the container body 210 is more stable.

[0081] When the guide protrusion moves in the third groove section 321c, the guide protrusion slides back and forth up and down in the third groove section 321c, which can drive the piston member 220 to move vertically in the brewing chamber to perform the above-mentioned first stroke H1, second stroke H2 and third stroke H3 respectively.

[0082] Furthermore, in one embodiment, the guide groove 321 further includes a fourth groove section 321d, and the fourth groove section 321d is arranged along the circumferential extension of the driving rod 320, and is respectively connected to the first groove section 321a and the end of the third groove section 321c away from the second groove section 321b. The first groove section 321a, the second groove section 321b, the third groove section 321c and the fourth groove section 321d are basically enclosed in a ring shape. Based on this, when the guide protrusion slides from the third groove section 321c along the fourth groove section 321d and finally slides to the first groove section 321a, the container body 210 is reset from the brewing position 120 to the powder receiving position 110.

[0083] When the guide protrusion moves in the third groove section 321c, the container body 210 is in the brewing position 120, and the guide protrusion slides back and forth up and down in the third groove section 321c, which can drive the piston member 220 to move vertically in the brewing chamber 211, adjust the position of the piston member 220 in the brewing chamber 211, perform a pressing stroke, or push the coffee grounds in the brewing chamber 211 upward.

At this time, the second driver 310 drives the driving rod 320 to rotate in the first rotation direction; when it moves from the connection between the fourth slot segment 321d and the first slot segment 321a to the second end of the second slot segment 321b, and further to the first end of 328b , the second driver 310 drives the driving rod 320 to rotate in the opposite direction in a second rotation direction opposite to the first rotation direction. In order to prevent the second slot segment 321b from reversing toward the second end of the second slot segment 321b and the guide protrusion from moving in the opposite direction to the third slot segment 321c when the second driver 310 is reversed at the first end of the second slot segment 321b and the connection between the fourth slot segment 321d and the first slot segment 321a, a limiting portion is provided at the second slot segment 321b and the connection between the fourth slot segment 321d and the first slot segment 321a, so that at the above two position points, even if the second driver 310 reverses its rotation, it will not return along the original path.

[0085] The third groove section 321c is provided with a brewing position point in its stroke. When the guide protrusion is located at the brewing position point, the piston member 220 and the second piston member 332 are arranged in the container body 210 for extraction. When the third groove section 321c continues to move upward and the guide protrusion is located at the connection between the third groove point 328c and the fourth groove section 321d, the piston member 220 pushes the extracted coffee grounds upward out of the container body 210.
